MEANS FOR OPENING OR CLOSING WATER-GATES.

SPECIFICATION forming part of Letters Patent No. 773,849, dated November 1, 1904. Application filed November 24, 1903. Serial No. 182,462. (No model.)

To all whmn it may concern:

Be it known that I, ADONIRAM J. COLLAR, a citizen of the United States, residing at Yreka. in the county of Siskiyou and State of California, have invented new and useful Improvements in Means for Opening or Closing ater-Gates, of which the following is a specification.

My invention relates to an improved appa ratus for opening and closing water-gates in mains, reservoirs, and the like. Its object is to provide a simple means for easily and quickly opening and closing gates either to be operated locally or automatically from a remote point. This means contemplates the use of, the water under control to effect the desired end.

The invention consists in the parts and the construction and combination of parts, as hereinafter more fully described, having reference to the accompanying drawings, in which -Figure l is a view of my apparatus shown partly in section. Fig. 2 is an end view of the inlet and outlet valves.

A represents a tank, of suitable size and material, disposed above the controlgate 2 in main 3 and adapted to be filled with water on occasion through the medium of a feed-pipe 4 and its continuationo, connecting the main above gate 2 and the bottom of the tank. Pipe-section 5 has one end screwed into a T 6, the latter being connected to the tank and having its opposite end closed by a screwplug 7, the T forming a suitable chamber for the operation of the float-valve 8, by which the admission of water to the tank is checked.

A suitable weighted annular float 9 is movable in tank A and when the latter is empty is normally supported on the valve-stem 10 to hold gate 2 closed by means of the tubular extension of the inner wall 11 of the float and the cap 11. Stem 10 extends centrally up through the tank and the float, being slidable in a tubular guide 12, rigid with the tank. By this arrangement of telescoping parts 11 and 12 the water is impounded in the tank without need of stuflfing-boxes or like frictioncausing devices, as would be necessary if the the tank.

The stem 13 of float-valve 8 extends up into the tank and is adapted to slide on or telescope with a supplemental stem 14, the upper end of which is bent over the rim of the float and adapted when the float rises to its highest point to be lifted, allowing valve 8 to rise and close the entrance to the tank. N ormally the stem portion 14 holds the valve open by gravity.

Pipe 4 enters pipe 5 intermediate of the ends of the latter. Discharge from one end of pipe 5, as we have seen, is controlled by the float-valve 8. Discharge from the opposite end is controlled by an externally-operated valve 15, actuated in unison with the feed-water inlet-valve 16 in pipe 4.

, The operation of valve 16 is effected by means of a stem 17 connected to lever 18, fulcrumed to a fixed support. Valve is connected with stem 17 by means of the external links 19.

In operation to open gate 2 lever 18 is lifted, causing valve 16 to open and valve 15 to close, thus admitting water to tank A, valve 8 being held open by the weight of stem-section 14. As the tank fills the float is gradually lifted, opening gate 2, and finally by raising stem 14 allowing float-valve 8 to rise in its chamber and prevent further ingress of water to the tank. Overflow from the latter is provided for at 20. so long as the float remains buoyed up gate 2 is held open. The size of the gate-opening may be varied by changing the length of stem 14, as by the turnbuckle 21, causing the valve 8 to close sooner or later in the upward movement of thefloat. To close gate 2 and shut off the head, lever 18 is thrown down, closing feed-valve 16 and opening the drain-valve 15. Thereupon the water in tank A is quickly discharged and the float falls and finally rests with all its weight on stem 10 to hold gate 2 closed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination with a water-gate, of a receptacle adapted to contain water, fluid connections between said receptacle and a source 1 I i l oi fluld-supply, a valve controlling flow 'trom said source of supply into said fluid connections, a valve controlling the inlet to said receptacle from said connections, and a discharge valve intermediate of said controlvalves, and means for operating the gate through the medium of the fluid in the receptacle.

2. The combination with a water-gate, of a receptacle adapted to contain water, fluid connections between said receptacle and a source of fluid-supply, a valve controlling flow from said source 01 supply into said fluid connections, a valve controlling the inlet to said receptacle from said connections, and a discharge valve intermediate of said controlvalves, means forgiving the first control-valve and said discharge-valve a synchronous movement, and means for operating the gate through the medium of the fluid in the receptacle.

3. The combination with a water-gate, ofa receptacle adapted to contain water, fluid connections between said receptacle and a source of fluid-supply, a valve controlling flow from said source of supply into said fluid connections, a valve controlling the inlet to said receptacle from said connections, and a discharge valve intermediate of said control valves, said inlet-control valve governable by the rise and fall of liquid in said receptacle, and means for operating the gate through the medium of the fluid in the receptacle.
